Study Summary

The PanOptix trifocal IOL is a new trifocal intraocular lens which is proved to provide good range of vision for distance, intermediate and near and good visual quality in cataract patients with normal axial length. But whether it can get the same visual quality in myopia is still unknown

Eligibility Criteria

Inclusion

Inclusion Criteria:

  1. Axial myopic patients（Refractive condition match the axial length after eliminate thenuclear cataract induced myopia factor）
  2. Corneal astigmatism <1.0D (IOL-Master 500/700, Carl Zeiss Meditec, Jena, Germany);
  3. Eyes with pupil diameter>2.5 mm (Photopic) and<6 mm (Mesopic) (Pentacam HR, OculusOptikgerate GmbH);
  4. Eyes with angle kappa<0.50 mm (Pentacam HR);
  5. Eyes with corneal spherical aberration<0.50 (Pentacam HR)

Exclusion

Exclusion Criteria:

  1. Irregular corneal astigmatism
  2. Any retinal disease, macular disease(Including myopic MD and retinal diseases) couldaffect VA, glaucoma and other severe intraocular diseases
  3. Moderate-severe dry eye
  4. Amblyopia（BCDVA<0.7 before cataract appears）
  5. Patients having difficulties with examinations or 3 months' follow-up.

Study Description

There are a few publications of multi-focal IOLs on Chinese patients with high myopia. From published papers, it is known that performance of multifocal IOLs is satisfied in myopic patients. However there is no publication to investigate PanOptix in moderate and high myopic patients. So it is imperative to demonstrate good performance of PanOptix in those special patients. The purpose of this study is to assess visual performance and patient satisfaction after the implantation of PanOptix in myopic patients.
